Othmer Library of Chemical History: Interlibrary Loan

The Donald F. and Mildred Topp Othmer Library is an independent research library.

Loaning to Other Libraries

The Othmer Library makes available modern materials for  interlibrary loan to patrons at other libraries. 

If a patron is interested in borrowing a book they should contact their affiliated library (university or public).


Our Library Symbol is C8F.

Document Delivery

The Othmer Library offers document delivery services. Document delivery encompasses articles, book chapters and some short documents. Items deemed too fragile will not be photocopied. All requested items must be cleared for copyright or be in the public domain. If you are not an OCLC participating library then please fill out an ALA form and submit it to documents@chemheritage.org  

Charges are $20.00 an item which includes the first 10 pages and 25 cents a page after that. 

Rare Materials

Pre-1850 imprints are not available for Interlibrary loan.  


For research- or publication-quality scans of the library's collection of rare and fragile materials, please contact digitallibrarian@chemheritage.org

Borrowing Privileges for Staff and Fellows

For CHF staff and fellows we have set up “direct requests,” this means that you will find the book or article you want in Worldcat and submit a request directly. Note: this is not the free Worldcat.org on the open web, but Worldcat Discovery (sounds fancy, right?). Worldcat Discovery IS fancy, it has replaced Firstsearch as OCLC’s search database. You can search for articles and books. If the Othmer Library owns what you are searching for, then it will appear at the top of the list (these you will still request through our catalog), if we don’t own the item then the record will allow you to place an ILL request. Worldcat Discovery indexes most journals and a lot of book chapters to allow you to request article titles. Of course, everything isn’t indexed so if you can’t find what you want then send me an email; the most likely culprits are going to be conference proceedings, industry journals and obscure historical citations. 


WorldCat Discovery can be reached through our catalog’s top navigation bar.  


Items that can be requested (not owned by us, not an e-book) will display a “Request Item” button; click then simply fill in your name, email and CHF status. 


Voilà! We will take care of the rest.

WorldCat Discovery is fairly new and direct request is new to us so please let us know if you have ANY problems!
