There are no current Early Literacy Guidelines. They are no longer posted on the APH website because they are being revised and and updated to reflect the new Formats. Therefore, the current guidelines in Formats are to be followed regarding double spacing.
The transcriber must determine if the circles, shadings, and other enhancements of item number/letters have any meaning. If this is merely decorative to visually emphasis the item number, ignore. If the transcriber determines that there is meaning added, use the shape indicator. However, as this single page appears to me, I would ignore.
