They have a Showcase Presents trade with the first 18 issues of SS that's been delayed. If they put 'em out at this rate, the relevant issues would be in volume three.
Honestly, the scanned page is the only appearance Oracle makes in #38. She's conspicuously absent in the next few issues, conspicuously because both Batman and Jim Gordon appear in #41 and Batman hangs around for the rest of that four-issue arc.
If you want to find Suicide Squad issues that feature Oracle, #48 and #49 would be my recommendation. Her first appearance since #38, and a two-parter that centers around her.
