+- Toying with correcting authors with trailing spaces via PostgreSQL:
+
+```
+dspace=# update metadatavalue set text_value=REGEXP_REPLACE(text_value, '\s+$' , '') where resource_type_id=2 and metadata_field_id=3 and text_value ~ '^.*?\s+$';
+UPDATE 20
+```
+
+- I tried the `TRIM(TRAILING from text_value)` function and it said it changed 20 items but the spaces didn't go away
+- This is on a fresh import of the CGSpace database, but when I tried to apply it on CGSpace there were no changes detected. Weird.
+- Anyways, Peter wants a new list of authors to clean up, so I exported another CSV:
+
+```
+dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'author') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/authors-2018-02-05.csv with csv;
+COPY 55630
+```
