    "body": "### Feature Request\n\n## Problem / Opportunity\nReading Log shelves (Want to Read, Currently Reading, Already Read, Stopped Reading) can only be sorted by date added. People with long Want to Read shelves want to pick their next book by title, age, rating, or popularity. Split out from #12695.\n\n## Proposal\nAdd four sort options to Reading Log shelves:\n\n| Option | `?sort=` value | Order | Solr field |\n|---|---|---|---|\n| **Title** | `title` | A–Z, ignoring case | `title` |\n| **First Published** | `old` | Oldest first | `first_publish_year` |\n| **Top Rated** | `rating` | Highest first | `ratings_sortable` |\n| **Most Wanted** | `want_to_read` | Most want-to-read logs first | `want_to_read_count` |\n\nThe `?sort=` values match the ones search already uses. Date Added (`desc`, the default) and Date Added oldest (`asc`) stay as they are.\n\n**Rule for missing data:** a book with no value for the chosen field (no publish year, no ratings, or not in Solr at all) goes after the books that have one, newest-added first. Nothing is ever dropped from the shelf.\n\n### Breakdown\n\n<details>\n<summary><strong>Implementation Details</strong> (start here)</summary>\n\n#### How it works today\nShelf membership lives in the `bookshelves_books` database table, not Solr. `Bookshelves.get_users_logged_books` (`openlibrary/core/bookshelves.py` ~line 341) has an inner function, `get_sorted_reading_log_books`, that selects one page of rows ordered by `created`, then fetches full book data for that page from Solr.\n\nTo sort by a book field, we need that field for *every* book on the shelf, not just one page. So the approach is:\n1. Select all of the shelf's rows (newest-added first).\n2. Fetch just the sort field for all of them from Solr in one request.\n3. Sort the rows in Python, then slice out the page.\n4. Hand that page of rows to the existing code, which fetches full book data as before.\n\n#### Related files\n* `openlibrary/templates/search/sort_options.html`: the `reading_log` block (~line 40)\n* `openlibrary/plugins/upstream/mybooks.py`: `ReadingLog.get_works_async` (~line 570) turns `?sort=` into the value passed down\n* `openlibrary/core/bookshelves.py`: `get_users_logged_books` and its inner `get_sorted_reading_log_books`\n* `openlibrary/templates/account/reading_log.html`: renders the sort menu (~line 72)\n\n#### Step by step\n\n**1. Add the options to the menu** in `openlibrary/templates/search/sort_options.html`, `reading_log` block:\n\n```python\nsort_options = [\n  { 'sort': 'desc', 'name': _('Date Added (newest)'), 'ga_key': 'DateAddedNewest' },\n  { 'sort': 'asc', 'name': _('Date Added (oldest)'), 'ga_key': 'DateAddedOldest' },\n  { 'sort': 'title', 'name': _('Title'), 'ga_key': 'Title' },\n  { 'sort': 'old', 'name': _('First Published'), 'ga_key': 'Old' },\n  { 'sort': 'rating', 'name': _('Top Rated'), 'ga_key': 'Rating' },\n  { 'sort': 'want_to_read', 'name': _('Most Wanted'), 'ga_key': 'WantToRead' },\n]\n```\n\n**2. Add the sort table and a sort function** at module level in `openlibrary/core/bookshelves.py`:\n\n```python\n# Reading Log sorts that need Solr data: ?sort= value -> (Solr field, descending)\nREADING_LOG_SOLR_SORTS = {\n    \"title\": (\"title\", False),\n    \"old\": (\"first_publish_year\", False),\n    \"rating\": (\"ratings_sortable\", True),\n    \"want_to_read\": (\"want_to_read_count\", True),\n}\n\n\ndef sort_reading_log_rows(rows: list, solr_docs: list, sort: str) -> list:\n    \"\"\"Order reading log rows by a Solr field; rows without a value keep their order, last.\"\"\"\n    field, descending = READING_LOG_SOLR_SORTS[sort]\n    values = {doc[\"key\"]: doc.get(field) for doc in solr_docs}\n\n    def value(row):\n        return values.get(f\"/works/OL{row['work_id']}W\")\n\n    present = [row for row in rows if value(row) is not None]\n    missing = [row for row in rows if value(row) is None]\n    if field == \"title\":\n        present.sort(key=lambda row: value(row).casefold())\n    else:\n        present.sort(key=value, reverse=descending)\n    return present + missing\n```\n\n**3. Use it in `get_sorted_reading_log_books`.** Find this line:\n\n```python\nreading_log_books: list[web.storage] = list(oldb.query(query, vars=query_params))\n```\n\nand replace it with:\n\n```python\nif sort in READING_LOG_SOLR_SORTS and bookshelf_id and not checkin_year:\n    all_rows = list(\n        oldb.query(\n            \"SELECT work_id, created, edition_id FROM bookshelves_books \"\n            \"WHERE bookshelf_id=$bookshelf_id AND username=$username ORDER BY created DESC\",\n            vars=query_params,\n        )\n    )\n    field, _ = READING_LOG_SOLR_SORTS[sort]\n    sort_docs = await get_solr().get_many_async([f\"/works/OL{row['work_id']}W\" for row in all_rows], fields=[\"key\", field])\n    offset = int(query_params[\"offset\"] or 0)\n    reading_log_books = sort_reading_log_rows(all_rows, sort_docs, sort)[offset : offset + limit]\nelse:\n    reading_log_books = list(oldb.query(query, vars=query_params))\n```\n\nEverything after that line (fetching full book data, handling redirects and deletes) stays as it is and now works on the sorted page.\n\n**4. Loosen the `sort` type hints.** `get_users_logged_books` and `get_sorted_reading_log_books` both declare `sort: Literal[\"created asc\", \"created desc\"]`. Change both to `sort: str`.\n\n**5. Pass the new values through** in `openlibrary/plugins/upstream/mybooks.py`, `get_works_async`. It currently collapses everything to `\"created desc\"` or `\"created_asc\"` (the underscore is a typo; it only works by accident). Replace that block with:\n\n```python\nif sort_order in READING_LOG_SOLR_SORTS:\n    sort_value = sort_order\nelif sort + \" \" + sort_order == \"created asc\":\n    sort_value = \"created asc\"\nelse:\n    sort_value = \"created desc\"\n```\n\npass `sort=sort_value` to `get_users_logged_books`, delete the `# type: ignore` and the Mypy comment above the old block, and import `READING_LOG_SOLR_SORTS` from `openlibrary.core.bookshelves`.\n\n**6. Hide the menu on yearly pages.** The Already Read year pages (`/people/<you>/books/already-read/2024`, the `checkin_year` path) already ignore sorting. In `openlibrary/templates/account/reading_log.html` (~line 71) change `$if not is_filtered:` to `$if not is_filtered and not checkin_year:` so the menu doesn't offer options that do nothing there. (The menu is already hidden while searching a shelf or filtering to ebooks.)\n\n**7. Add tests.** Create `openlibrary/tests/core/test_bookshelves.py`. `sort_reading_log_rows` is a plain function: pass rows like `{\"work_id\": 1}` and Solr docs like `{\"key\": \"/works/OL1W\", \"title\": \"Apple\"}`. Cover:\n* each of the four sorts, in the right direction\n* `title` ignores case (`\"apple\"` before `\"Banana\"`)\n* a row whose work has no Solr doc, and a row whose doc lacks the field, both end up last in their original order\n* ratings and counts of `0` are kept and sorted, not treated as missing (`0` is not `None`)\n\nRun them with:\n```bash\nmake test-py-uv PYTEST_ARGS=\"openlibrary/tests/core/test_bookshelves.py\"\n```\n\n**8. Check it by hand.** In the dev environment (`docker compose up`, log in as `openlibrary` / `openlibrary`), add 5+ books to Want to Read, then visit `/people/openlibrary/books/want-to-read?sort=title` and try each option from the menu. Check that the shelf count doesn't change between sorts, that page 2 keeps the sort (with 26+ books; the page size is 25), and that `?sort=asc` / `?sort=desc` still work.\n\n#### Requirements Checklist\n* [ ] Title, First Published, Top Rated, and Most Wanted options on every shelf\n* [ ] Books missing the sort value come last; none are dropped (the shelf count never changes)\n* [ ] Date Added (newest/oldest) behaves as before\n* [ ] The selected sort is kept when paging\n* [ ] Sort menu hidden on yearly Already Read pages\n* [ ] Tests for `sort_reading_log_rows` pass\n* [ ] `pre-commit run --files <changed files>` passes\n\n#### Stakeholders\n*\n\n<hr>\n\n#### Instructions for Contributors\n* **Before** [creating a new branch](https://docs.openlibrary.org/developers/tools/git.html#making-changes-and-creating-a-pull-request) or pushing up changes to a PR, please first [run these commands](https://docs.openlibrary.org/developers/tools/git.html#working-on-your-branch) to ensure your repository is up to date, as the pre-commit bot may add commits to your PRs upstream.\n\n</details>\n",
