I am currently working on an inquisition report by the Archbishop of Manila made in 1686. The PDF of the document is supplied by the Spanish archives of the Indies.
As I prefer to work on printed documents, I tried to have the file printed by Lulu as a private book, but the Spanish PDF was refused because its margins varied.
I therefore created a WordPerfect copy, each page of the PDF being imbedded as a picture in the WP file. Its total number of pages was made divisible by 4 by adding the necessary blank pages at the end.
As it is too large, I had to divide it into 4 sub-files.
I uploaded the batch to Lulu through SmartFTP. In Lulu, these files are listed in the order of reception, the one at the top of the heap being D. I selected the four files together and had them copied in my project.
I thought Lulu would print the file in the right order: ABCD. It didn't. Instead, they are printed in the reverse order: DCBA!
This is an interesting experience that taught me a lesson. I should have had the files copied separately in the project: first A, then B, then C, and finally D. I'll make a new edition to see if they are printed in the right order, ABCD.
A secondary and minor consequence is that the extra blank pages at the end of D being now inside the book, and the last page of A not being blank, the printer had to add 5 blank pages to make the new total divisible by 4.
