Let's say I want to build a DDC number for The Texas Flower Garden: Seasonal Guide to Bloom, Height, Color, and Texture, which has the LCSH:
I look for "Gardens" in the Relative Index, find 635 Garden crops (Horticulture), and click START in that record, without taking time to look at the main subdivisions of 635 in the hierarchy box:
635.1-635.8 Edible garden crops
635.9 Flowers and ornamental plants
Belatedly, I remember that I should have looked for flowers or ornamental plants. When I do look, I realize that I should have started with 635.9 Flowers and ornamental plants. The Relative Index entries "Flower gardening," "Flowers--gardening," and "Ornamental plants" all point to 635.9. I select 635.9, but before I can use 635.9 as base number, I need to click CANCEL in the Create Built Number box, which still holds 635:
I find and select T2--764 Texas and click ADD; then I get an error message:
I belatedly recall that I need to find the add note in Table 1. First I must click the X in the red circle in the Create built number box to delete + T1--09 History, geographic treatment, biography and revert to only the base number 635.9:
Now when I find and select T2--764 Texas, then click ADD, I get the desired result:
The "then add further as follows" part of the add note allows me to add further to express that the book is a pictorial work. In the add table under T1--093-T1--099 Specific continents, countries, localities; extraterrestrial worlds I select 022 Illustrations (also known as T1--093-T1--099:022) and click ADD:
Now the number building process is complete. I can click SAVE and go on to review / revise the user terms that index the built number.Note: We have encountered rare circumstances where the number building tool has become confused by multiple layers of backing out. If things go awry, you can always click CANCEL and do what you really meant to do in the first place.
