The local library that used the Dewey decimal system, and an academic library that used the Library of Congress system. The LC call system was a far superior system. Using letters and numbers makes everything easier to read and understand.
I would give each era a letter
I you need to add an era in between C and D, it would be CA
Then give each major book a number divisible by 10 [10, 20, 30...]
Use the 1's space to denote novellas and short stories.
Then place a decimal point, after which you could put series and number in that series. This way you are using the area before the decimal to create a timeline, and the area after the decimal to show a basic description.
