# MARC 导入滤件规则

EndNote 导入 MARC 记录时遵循如下规则：

* 当为 MARC 记录设计滤件时，EndNote 仅允许指定的前三个标签。可以不理会空格和数字后的前三位数值。下面的例子的标签是 245：

`245 10  $a When you realize you have too many`\
`kids: $b a guide / $c Hugh B`

`245 14  $a The angel with a dirty mouth /$c NickSteel ; illustrated by Melissa`

* 不必在一个标签行定义一个了域。可能有一些包含不想导入到 EndNote 数据库的子域。EndNote 忽略在滤件中没有定义的任何子域
* 数据文件的数据行不能利用「Smart Source Parsing」 选项。但是可以在源数据行输入子域的多种变量。确保在同样的标签后(不必每次重复标签)输入所有子域，并列出最复杂的子域格式列表。例如：

`773 $gVolume(Issue), p.`

* 与文献类型标签不同的是，EndNote 允许一次定义一个标签。因此应该包括想导入的包含数据的所有子域。例如下面在 MARC 记录的滤件中的数据行会成功导入

| Tag | Field(s)                   |
| --- | -------------------------- |
| 245 | $a Title $b Title $c Notes |

`245 14  $a The hollow horn : $b Bob Dylan's reception in the United States and Germany / $c by Dennis Anderson.`

`245 10  $a Bob Dylan, spellbinding songwriter /$c Nathan`

`245 00  $a Down in the groove.`
