NLM's Book Grant Came Back After Seven Months Dark — and the Word 'Historians' Is Gone From the Description

There is exactly one NIH funding mechanism whose deliverable is a book. The G13 — NLM Grants for Scholarly Works in Biomedicine and Health — has run near-continuously since at least 2007 under a chain of parent announcements: PAR-07-237, PAR-09-030, PAR-11-084, PAR-13-014, PAR-14-339, PAR-16-417, PAR-19-032, PAR-21-046, PAR-23-183. It funds the preparation of book-length manuscripts: critical reviews, state-of-the-art summaries, historical studies, and other durable organizations of knowledge in clinical medicine, public health, biomedical research, and informatics.

PAR-23-183 expired February 27, 2026. For seven months, nothing replaced it. In the interim NLM published NOT-LM-26-002, a Request for Information on the future direction, scope, and structure of the program, with responses due August 18, 2026. When a small, long-running program goes dark and its institute asks the field what the program should be, the outcome is rarely a clean reissue.

On September 24, 2026, NLM answered. PAR-28-027, NLM Grants for Scholarly Works in Biomedicine and Health (G13 Clinical Trial Not Allowed), posted as a forecast.

What the forecast actually says

Note that 4 × $80,000 = $320,000 exactly. NLM has published a fully self-consistent budget, which is unusual and useful: it means the ceiling is not aspirational. Four awards, all at or near the maximum, is the planned shape. It also means the $10,000 floor is doing real work. A $10,000 G13 is a plausible award — a short sabbatical supplement, a manuscript-completion grant, an indexing-and-permissions budget — and an applicant requesting $18,000 for a genuinely bounded scope is not disadvantaged by being small. In a four-award pool, one modest well-scoped request is easier for a council to accommodate than a fifth $80,000 ask.

The description changed, and the change is specific

Here is PAR-23-183's synopsis description, as filed:

...the preparation of book-length manuscripts and other works of academic and/or public health importance to U.S. health professionals, public health officials, biomedical researchers and historians of the health sciences.

Here is PAR-28-027's forecast description:

...the preparation of book-length manuscripts and other scholarly works of academic and/or public health importance to U.S. health professionals, scientists, public health professionals, and other relevant audiences... critical reviews, analytical syntheses, and other integrative scholarly works that organize, contextualize, and disseminate biomedical and health-related knowledge.

The named audience "historians of the health sciences" is gone. So is the program's longstanding gesture toward scholars working at the intersection of digital humanities, data science, and the history of the health sciences. What replaces it is "scientists," "other relevant audiences," and a work-type list — critical reviews, analytical syntheses, integrative scholarly works — that describes synthesis of the current evidence base rather than historical study.

A forecast description is not the announcement. It is a summary written months before the full NOFO, and forecast metadata is thinner and drafted faster than final text. It is entirely possible that history-of-medicine language returns in the February 2027 posting. But this forecast was written after an RFI specifically asking the field about the program's future scope, which makes the omission a deliberate drafting choice rather than an accident of brevity. Historians of medicine planning a G13 submission should treat the February 2, 2027 posting as a scope check, not a formality — and should read the eventual announcement before investing in a specific-aims framing built on historiography.

The eligibility metadata shifted too. PAR-23-183's "other eligible applicants" list named Alaska Native and Native Hawaiian Serving Institutions, AANAPISIs, Hispanic-Serving Institutions, HBCUs, and Tribally Controlled Colleges and Universities alongside federal agencies, territories, faith- and community-based organizations, regional organizations, and foreign institutions. PAR-28-027's forecast list retains the tribal governments, federal agencies, territories, faith- and community-based organizations, regional organizations, and non-domestic (non-U.S.) entities — and drops every minority-serving-institution designation. The broad applicant-type table is otherwise unchanged and still includes higher education, nonprofits with and without 501(c)(3) status, small businesses, for-profits, and state and local governments. MSIs remain eligible through those general categories; what changed is whether they are named. Given the wider federal drift on categorical designations in 2026, that is a change worth noting rather than assuming is clerical.

The one thing that plainly did not change: foreign institutions remain eligible. For an NIH mechanism, that is rare, and it is the most underexploited fact about the G13.

The ceiling moved. In real terms it fell.

PAR-23-183 carried a $75,000 award ceiling. PAR-28-027 forecasts $80,000 — a 6.7% nominal increase over a three-year gap. Against cumulative inflation since the 2023 posting, that is a real-terms reduction. For a mechanism whose primary cost is release time for a scholar, the practical consequence is straightforward: $80,000 buys less course buyout in 2028 than $75,000 bought in 2023.

The response is not a bigger ask — the ceiling is the ceiling. It is a tighter scope. Applications that promise a completed 400-page monograph on an $80,000 total budget have always strained credibility; at 2028 salary levels they strain it further. Applications that fund a defined, completable segment — the archival research phase, the final two chapters, the permissions-and-image-rights budget, the translation — are both more credible and more consistent with the program's actual award history.

Nineteen months from forecast to first dollar

Trace the published timeline: forecast September 24, 2026 → full announcement February 2, 2027 → application due May 25, 2027 → award April 1, 2028 → project start April 1, 2028. That is 19 months from today's notice to the first dollar, and eight months from today to the application.

This is the fundamental arithmetic of a forecast, and it is why forecasts are the most underused document in federal grantseeking — a point that applies just as much to NIEHS's children's environmental health center recompete, forecast the same week. There is no application package to download and nothing to submit, so nearly nobody acts. Meanwhile the work that actually decides a G13 application takes most of a year.

What that work is, concretely:

Secure the publisher. A G13 is judged in part on whether the work will reach its audience. A letter of interest from a university press, or an executed contract, is the single strongest non-narrative element an applicant can produce — and press acquisition timelines run months, not weeks. Starting that conversation in April 2027 is starting it late.

Do the archival or literature reconnaissance now. Reviewers can distinguish a proposal written by someone who has been in the sources from one written by someone who intends to be. Eight months is enough to complete a pilot chapter. A drafted chapter is the most persuasive appendix a book proposal can carry.

Resolve the institutional question early. The G13 is an institutional grant, not a fellowship paid to an individual. An independent scholar needs a sponsoring eligible organization, which means a UEI, SAM.gov registration, an eRA Commons account, and an office of sponsored programs willing to process a grant whose deliverable is a manuscript. That last part is a real obstacle at institutions whose research administration is built entirely around clinical and laboratory awards. Start the conversation now, because a research office encountering the G13 for the first time in May 2027 will not move at your pace.

Calendar February 2, 2027. The forecast's estimated posting date is when you learn whether the scope language above narrowed on paper or only in the summary. Everything above is provisional until that document exists.

Who this is actually for

Four awards. $320,000. In an agency that obligates tens of billions annually, the G13 is a rounding error — which is exactly why it is worth a strategist's attention. The applicant pool for a book grant is small, largely self-selecting, and populated by scholars who mostly do not think of themselves as NIH applicants at all.

The people best positioned for the May 2027 deadline are the ones who can answer one question in a sentence: what is the specific, completable scholarly work, and who will publish it? If you can answer that today, you have eight months to build the rest. If you cannot, the forecast has just given you eight months to figure it out — which is the entire point of reading forecasts.
