Ionic channels of excitable membranes / Bertil Hille. (OCLC #10755486)
This gift book was already labeled with a call number that didn’t quite look like a Library of Congress call number. It was in the copy we found as a National Library of Medicine call number:
060 __ ǂa QH 601 ǂb H651i 1984
We re-labeled with a Library of Congress call number, which was quite similar:
050 00 ǂa QH601 ǂb .H55 1984
The two classifications are similar enough that in our collection, we do have some titles with NLM call numbers assigned, but interfiled with the LC collections.
