+- Create a PostgreSQL 14 instance on my local environment to start testing compatibility with DSpace 6 as well as all my scripts:
+
+```console
+$ podman pull docker.io/library/postgres:14-alpine
+$ podman run --name dspacedb14 -v dspacedb14_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:14-alpine
+$ createuser -h localhost -p 5432 -U postgres --pwprompt dspacetest
+$ createdb -h localhost -p 5432 -U postgres -O dspacetest --encoding=UNICODE dspacetest
+```

+- Peter sent me a list of items that had ILRI affiation on Altmetric, but that didn't have Handles
+  - I ran a duplicate check on them to find if they exist or if we can import them
+  - There were about ninety matches, but a few dozen of those were pre-prints!
+  - After excluding those there were about sixty-one items we already have on CGSpace so I will add their DOIs to the existing items
+    - After joining these with the records from CGSpace and inspecting the DOIs I found that only forty-four were new DOIs
+    - Surprisingly some of the DOIs on Altmetric were not working, though we also had some that were not working (specifically the Journal of Agricultural Economics seems to have reassigned DOIs)
+- An unscientific comparison of duplicate checking Peter's file with ~500 titles on PostgreSQL 12 and PostgreSQL 14:
+  - PostgreSQL 12: `0.11s user 0.04s system 0% cpu 19:24.65 total`
+  - PostgreSQL 14: `0.12s user 0.04s system 0% cpu 18:13.47 total`
