I strolled down the long aisle until I reached Shelf 34 and proceeded to narrow down the search until I saw the tag [915.113 – 915.69] on the bottom-most shelf of the rack. Because my book was less than 100 pages, there wasn’t space to print anything on the spine, which made spotting it among all the other books slightly challenging.
After playing a very short game of Where’s Wally, I managed to find it and fish it out. (Note to self: Make sure that the next book I write has at least 100 pages. Anything less feels like a fancy booklet instead of a proper book.)
(This visit was made in April, before “Phase 1.5” restrictions came into effect on 16 May)
