I tend to read the books i validate. So I have several in progress at a
time and tend to upload several at a time. I know this keeps them from
being available for others to work on but I work on all of them during the
time they are with me.
Part of my reason for doing this is I like reading fiction and nonfiction
for example and so have one of each. Sometimes I take a longer time
working on a long book or a book with difficult issues of some sort and
like having other books around to read.
