Drop, Switch, and Find!

Some books I found recently have had their digits switched or shelved as if half of the number was dropped:

• ·         N5630 .R49 1974 shelved as N6530 .R49 1974
• ·         HV4945 .K53 1926 shelved as HV49 .K53 1926

A common rule of thumb when it comes to searching is to be aware that these things happen, so be prepared for it and think about how the numbers can be dropped and switched!

Good luck and happy searching!
